A P0302 code on your 2019 Ford Explorer indicates the PCM detected misfires in cylinder 2. The 2019 was the final year of the 5th generation Explorer, offering different engines than the current generation.
2019 Explorer Engine Options
The 2019 Explorer offered the 3.5L V6, 2.3L EcoBoost 4-cylinder, and 3.5L EcoBoost V6. The naturally aspirated 3.5L is more traditional, while EcoBoost engines have turbo-related considerations.
Age-Related Considerations
At 5+ years old, the 2019 Explorer may experience misfire from wear items—spark plugs, ignition coils, and potentially carbon buildup on EcoBoost models. Check maintenance history for service intervals.
Cylinder 2 Location by Engine
On the 3.5L V6 (both versions), cylinder 2 is on the front bank (passenger side). On the 2.3L EcoBoost 4-cylinder, cylinders are numbered 1-4 front to rear with cylinder 2 being second from front.
Diagnostic Approach
The coil-on-plug design allows easy swap testing on all engine options. This test quickly identifies whether the ignition coil is the misfire source without buying parts first.
